VALVE AND COCK.

Specification of Letters Patent.

Patented Nov. 10, 1908.

Application :filed May 20, 1907. Serial No. 374,684.

To all whom it may concern:

Be it known that I, JACOB ANDERSON, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Valves and Cocks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciiication.

This invention relates to improvements in valves and cocks, and is shown embodied'as a gas valve or cock, though adaptable for many other uses.

In gas valves or cocks as heretofore constructed it has been impossible for the owner or mistress when leaving a servant or children in charge or in the house to adjust the individual jets to revent the servant, child or any other unaut orized person from turning on the gas, or to adjust the gas jet to permit the gas to be burned until turned off and to prevent turning it on again by the same key whereby it was turned 0H.

It is an obj ect of this invention to provide a valve having a plurality of coacting closures, any of which acts to cut 0H the gas but only one of which can turn it on again.

It is a further object of this invention to provide a simple, durable and cheap valve adapted for use wherever desired to prevent unauthorized opening of the same.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a similar view taken at a rightangle with the same. Fig. 3 is a section taken on line 8 3 of Fi 2. Fig. 4 is a section taken on line 4-4 o Fig. 3. Fig. 5 is a fragmentary section showing the valve closed by actuation of either plu Fig. 6 is a fragmentary section with t e outer or opening plug in the same position as shown in Fig. 5 and illustrating the effects whenthe inner plug is rotated.

As shown in said drawings: A, represents a casing of any suitable size and material and which is rovided with an internally threaded inlet en a, for connection with the supply pipe a', and an externally threaded outlet end a2, in alinement with the inlet end and adapted for engagement with the gas jet a3,

or another pi e. Said casing is provided with a conically tapered bore and rotatably engaged therein is an outer hollow tapered plug closure B, having oppositely disposed transverse apertures ada ted to register with the inlet and outlet of t e casing. Integral with said closure is an actuating key b, and a stopb', is threaded into or otherwise provided on the closure and at its limits of movement abuts against shoulders liz-b3, as shown formed by cutting a recess in the casing A and which indicates open and closed positions respectively. A washer b4, is engaged on the smaller end of the plug closure,

against which bears a nut 55, threaded on the 1 end of said closure and preventing longitudinal movement thereof.

`Rotatably enga ed in the complemental l bore in said plug c osure B is a plug closure C having less taper and having a wing or key c for manual actuation. A pin c', or other suitable shoulder is rigidly engaged to said plug closure C and is ada ted to abut against shoulders or sto s (J2-c3 ormed as shown by recessing the tlfreaded end of the tubular plug closure B. The op osite end of said plug closure is reduced in iameter and fitted on said reduced end is a washer D having an integral stop d which contacts at its opposite limits of movement shoulders or stops d-cl2 at the same end of the casing and beneath the 'aforesaid shoulders liz- 113, and a nut d3 is threaded into the end of the plug closure C and firmly secures said Washer in place.

The operation is as follows: In the position shown in Fig. 3 the plug valve closures B and C are both turned to their extreme right hand position and the stop c, on the closure C abuts against the shoulders c2 on the end of the plug closure B and in this position the apertures through said closures are in alinement with each other and with the inlet and outlet. The valve may now be turned 0H by actuation of either closure but can then only be turned on by actuation of the plug closure B. When the closure B is rotated to the left it carries said closure C which is contained therein, with it until the stop b abuts against the shoulder b3 in which osition the valve is closed. On the other and if the plug closure C is rotated to the right from the position shown in Fig. 3 it likewise rotates the closure B by the stop c engaging the shoulder c2 on the lug B rotating both until the stop b engaged) to the closure B engages Q scalesI the stop t3, as before described and itis obclosure engages the shoulder d2, thereby pre-V venting further rotation of the plug closure, which would otherwise rotate said vplug B until the apertures were in register with the inlet and outlet to open the cock.'V The plug C may be rotated in either direction without Vopening the valve, the stop d limiting its movement by abutting against the shoulders d-CZ2.V To open the valve the plug B must be rotated to the right when the shoulders2 engaging the pin c on the plug C both closures simultaneously rotate to open position. For the purpose of preventing an r one but the authorized person from opening the valve a small casing may be built to inclose the actuating key b for the plug B.'

lChanges in construction may be made and I therefore do not desire to limit this application otherwise than necessitated by the prior art.

I claim as my invention:

1. In a valve the combination with coacting valve closures adapted by vactuation of either to close-the valve and parts on one closure contacted n by parts on the' other whereby actuation of one of the closures adjusts both to open position.

2. A valve comprising coacting closures one only of which is adapted to open the valve.

3. A valve comprising rotatableplug closures, either oli' which is adapted to close the valve and only one of which is adapted to open the valve. l

Ll. A valve comprising a plurality of concentric rotatable plug closures, means limiting the movement thereof in opening the va ve and one of said closures adapted by actuation thereof to adjust all of the closures to open position. v

5. In a valve oi the class described the combination with a casing of coacting closures therein, one o1C said closures adapted to close the valve and the other closure adaptedV to openthe valve independently of actuation of the rst named closure.

6. In a valve the combinationwith a casing of a hollow plug closure therein having oppositely disposed apertures, a plug closure journaledin said hollow closure and also having oppositely disposed apertures which are adapted to register with those of the other closure, a wing or'lrey on each plug adapted when either is actuated to operate the clo- Y sures to close the valve, said valve opened by actuation of one only of the closures and.V

stops limiting the movement of Vsaid closures.

i 7. In a device of the class described the combination with a valve casing of a plurality of closures therein, eachprovidedfwith apertures, meansV for. actuating roneV of said` closures to bring said -apertures in alinement to open the valve, lsaid valve closed by .actuation ci either closure.V

8. In a device of the.. class described the combination with casing of 'interiitting valve closures therein and each apertured7 Y means'for manually actuating one of the clesures to close the valve and the otherclosure to bring said apertures into register to open the valve and means limiting the movement,

of each closure in opening the valve. g Q. A valve comprising a casing having a threaded outlet and a vthreaded inlet and a plurality of interfitting plug closures in said casing either adapte'dfrto be manually actu-V` Y ated to close the valve and one of said plug.

closures adapted to open the valve after the valve has been closed by either closure. Y

10. A gas valve or the like comprising a casing and two closures theretor.each'adapted.v

to close the valve independently of the other, f

' open position.

12. A` gas valve or the like comprisingxaVV casingan d two valve closures .therein7 either adapted to close the valve and one only to open the valve, mutually engaging'external parts on said valve olosureswhereby actuation of the .opening valve. closure adjusts both to open position and means at each end el the closures for securing the saine in operative position.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
